Hi,

I am getting a weried message, as it was working fine few days back, but some who its start showing the old data, as well as the admin section I am not able to login

The message is showing:

Warning: fopen(/home/cj/public_html/files/cache_objects/object_79516840c559c240e999cac81961853b) [function.fopen]: failed to open stream: Permission denied in /home/cj/public_html/concrete/libraries/cache/default.php on line 44

Warning: fputs(): supplied argument is not a valid stream resource in /home/cj/public_html/concrete/libraries/cache/default.php on line 45

Warning: fclose(): supplied argument is not a valid stream resource in /home/cj/public_html/concrete/libraries/cache/default.php on line 46

I already updated the permission to 777

What should I do
